1)scala 时间格式转换(String、Long、Date)
1、时间字符类型转Date类型
[java] view plain copy import java.text.SimpleDateFormat val time = "2017-12-18 00:01:56" val newtime :Date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(time) println(newtime) //output:Mon Dec 18 00:01:56 CST 2017
2、Long类型转字符类型
[java] view plain copy val time:Long= 1513839667//秒 val newtime :String = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(time*1000) println(newtime) //output:2017-12-21 15:01:07
3、时间字符类型转Long类型
[java] view plain copy val time = "2017-12-18 00:01:56" val newtime :Long= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(time).getTime println(newtime) //output:1513526516000
2)scala 时间和时间戳互转
时间转换为时间戳:
import java.text.SimpleDateFormat
object test {
def main(args: Array[String]): Unit = {
val tm = "2017-08-01 16:44:32"
val a = tranTimeToLong(tm)
println(a)
}
def tranTimeToLong(tm:String) :Long={
val fm = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
val dt = fm.parse(tm)
val aa = fm.format(dt)
val tim: Long = dt.getTime()
tim
}
}
时间戳转化为时间:
import java.text.SimpleDateFormat
import java.util.Date
object test {
def main(args: Array[String]): Unit = {
val tm = "1502036122000"
val a = tranTimeToString(tm)
println(a)
}
def tranTimeToString(tm:String) :String={
val fm = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
val tim = fm.format(new Date(tm.toLong))
tim
}
}
